3. • learning how to compose and manipulate
spreadsheets is a useful tool for any type of data
organization including social science research,
public health research, and medical research.
• Some of the major advantages of using a
spreadsheet are that repetitive calculations can
be duplicated with just a few keystrokes,
mistakes in calculations can be fixed by changing
single cells or functions, and data is organized in
a clear and understandable way

19. • All calculations in the
spreadsheet must begin with
an equals sign, indicating to
the program
that you are performing a
calculation. Below is a table
listing some of the basic
mathematical
operations and the
correlated commands.

22. Useful Commands
1. Average
To compute the average value of a set of numbers, use the =AVERAGE(fifirst cell:last cell)
command.
2-Standard deviation
Calculating the standard deviation is very similar to calculating the average value of a data
set.
Just type =STDEV(fifirst cell:last cell)
3-Count cells
If you have a long list of cells and want to determine the N value (number of data points) for
future calculations, use the =COUNT(array of cells) command.
4-t statistic
To compute the student t statistic use the =TINV(probability, DOF) command, where DOF
is the number of degrees of freedom (N-1) and probability is 1-(confifidence limit).
